BEND, OR -- Deschutes County Sheriff Shane Nelson fired two more supervisors, Thursday. Robert Trono, a Lieutenant in the Corrections Division, was placed on paid leave September second. Patrol Sgt. Dan Bilyeu was put on leave February 21.

Sheriff Nelson tells KBND News, "The termination was a result of internal investigations that concluded policy violations had occurred. The policy violations were regarding on-duty conduct that was not criminal in nature." Sheriff Nelson would not elaborate, other than to say the two were involved in separate investigations. "I’m going to release more specific information at a later date, once the separation process is concluded," says Nelson. "There’s one more step that’s offered to the employee after a consequence has been determined."

Lt. Trono was the focus of an ATF investigation last year, following complaints he built a firearm for a co-worker while off-duty, without a license; although it was determined not to be a prosecutable offense. He’s also named in a civil suit filed by the family of an inmate who died of a drug overdose while in custody. The lawsuit claims as jail commander, Trono failed to schedule adequate medical staff.

A deputy was fired last month. And, In the past 14 months, the Sheriff's Office has lost three captains - one fired, one resigned amid an investigation and one retired.
